Technical field

Embodiments of the present invention generally relate to communication systems, and more particularly, to systems and methods for a semi-non-DRx mode.

Wireless communication systems have become an important means for many people around the world to communicate. A wireless communication system may provide communication for a number of subscriber stations (e.g., user equipment, mobile phones, smart phones, tablets, etc.), and each of the subscriber stations may be served by a base station. The subscriber station may communicate with one or more base stations via transmissions on the uplink and downlink. The uplink (or reverse link) refers to the communication link from the subscriber station to the base station, and the downlink (or forward link) refers to the communication link from the base station to the subscriber station.

Efficient use of power resources has become more important as users continue to use their subscriber stations at increasing rates. Efficient use of power enables unblocked communications and a better user experience. Some current systems enable subscriber station power conservation, while also introducing network latency. These delays may occur if the subscriber-station only monitors a particular paging channel. Delays in these present systems are undesirable because they may have a negative impact on data transmission and user experience.

Indeed, embodiments of the present invention provide power-efficient devices, systems, and methods that can mitigate time delays. Doing so can not only efficiently utilize power resources, but can also help to minimize delays associated with network communications.

More and more people are using wireless communication devices such as, for example, mobile phones for voice communications as well as data communications. In the GSM / EDGE (Global System for Mobile Communications / Enhanced Data Rates for GSM Evolution) radio access network (GERAN) specification, General Packet Radio Service (GPRS) and Enhanced General Packet Radio Service (EGPRS) provide data services.

Global System for Mobile Communications (GSM) is a widely spread standard in cellular and wireless communications. GSM is relatively efficient for standard voice services. However, high-fidelity audio and data services require higher data throughput rates than GSM is optimized. In order to increase performance, General Packet Radio Service (GPRS), Enhanced Data Rates for GSM Evolution (EDGE) alc UMTS (Universal Mobile Telecommunications System) standards have been adopted in GSM systems. In the GSM / EDGE radio access network (GERAN) specification, GPRS and EGPRS provide data services.

Standards for GERAN are maintained by the Third Generation Partnership Project (3GPP). GERAN is part of GSM. More specifically, GERAN is the wireless portion of GSM / EDGE with the networks participating in base stations 102 (Ater and Abis interfaces) and base station controllers (A interfaces, etc.). GERAN represents the core of a GSM network. It routes telephone calls and packet data to and from the PSTN (Public Switched Telephone Network) and remote terminals to / from the Internet. GERAN is also part of the combined UTMS / GSM networks.

FIG. 1 illustrates an example of a wireless communication system 100 in which the systems and methods disclosed herein may be utilized. The wireless communication system 100 includes a plurality of base stations (BS) 102 and a plurality of wireless communication devices 104. Each base station 102 provides communication coverage for a particular geographic area 106. The term "cell" may refer to base station 102 and / or its coverage area 106 depending on the context in which the term is used.

As used herein, the term "wireless communication device" refers to an electronic device that can be used for voice and / or data communication over a wireless communication system. Examples of wireless communication devices 104 include, but are not limited to, cellular phones, personal digital assistants (PDAs), handheld devices, wireless modems, laptop computers and personal computers, machine type communications (MTC) To-machine (M2M) devices and sensor devices (including, for example, so-called "smart-meters ", alarm and health monitoring devices). The wireless communication device 104 may alternatively be an access terminal, a mobile terminal, a mobile station, a remote station, a user terminal, a terminal, a subscriber unit, a subscriber station, a mobile device, a wireless device, a user equipment (UE) , ≪ / RTI > or some other similar term. Although the term MTC device is used below to illustrate the benefits that may be achieved in MTC devices, the gains may also be achieved for other wireless communication devices 104 as well.

The term "base station" refers to a wireless communication station that is installed in a fixed location and used to communicate with wireless communication devices 104. The base station 102 may alternatively be referred to as an access point (including a nano-cell, a pico-cell and a femto-cell), a Node B, an enhanced Node B, a Home Node B, or some other similar term.

To improve system capacity, the base station coverage area 106 may be partitioned into a plurality of smaller areas, e.g., three smaller areas 108a, 108b, and 108c. Each smaller area 108a, 108b, 108c may be served by a respective base transceiver station (BTS). The term "sector" may refer to a base transceiver station (BTS) and / or its coverage area 1086, depending on the context in which the term is used. For sectorized cells, base transceiver stations (BTS) for all sectors of the cell are typically co-located within the base station 102 for the cell.

The wireless communication devices 104 are typically interspersed throughout the wireless communication system 100. The wireless communication device 104 may communicate with one or more base stations 102 on the downlink and / or uplink at any given moment. The downlink (or forward link) refers to the communication link from the base station 102 to the wireless communication device 104 and the uplink (or reverse link) refers to the communication link from the wireless communication device 104 to the base station 102 Quot; The uplink and downlink may refer to a carrier used for a communication link or a communication link.

In the case of a centralized architecture, the system controller 110 may couple to the base stations 102 and provide coordination and control for the base stations 102. The system controller 110 may be a single network entity or a collection of network entities. For a distributed architecture, base stations 102 may communicate with each other as needed.

It is desirable for the wireless communication device 104 to use a minimal amount of power to extend the battery life of the subscriber station. It is also desirable that any delays be minimized (to improve the user experience of the subscriber station). Thus, advantages may be realized by systems and methods that efficiently minimize delays while maximizing battery life for wireless communication devices 104. [ These advantages may be realized by the wireless communication devices 104 and the corresponding base stations 102.

2 shows a block diagram of a transmitter 211 and a receiver 213 of a wireless communication system 100 in accordance with some embodiments of the present invention. For the downlink, the transmitter 211 may be part of the base station 102 and the receiver 213 may be part of the wireless communication device 104. In the case of an uplink, the transmitter 211 may be part of the wireless communication device 104, and the receiver 213 may be part of the base station 102.

At the transmitter 211, a transmit (TX) data processor 234 receives and processes (e.g., formats, encodes, and interleaves) the data 201 and provides coded data. A modulator 212 performs modulation on the coded data and provides a modulated signal. The modulator 212 may perform Gaussian minimum shift keying (GMSK) for GSM and 8-ary phase shift keying (E-PSK) for Enhanced Data Rates for Global Evolution (EDGE). GMSK is a continuous phase modulation protocol while 8-PSK is a digital modulation protocol. A transmitter unit (TMTR) 218 conditions (e.g., filters, amplifies, and upconverts) the modulated signal and generates an RF modulated signal that is transmitted via the antenna 220.

At receiver 213, antenna 222 receives RF modulated signals from transmitter 211 and other transmitters. Antenna 222 provides a received RF signal to a receiver unit (RCVR) 224. A receiver unit 224 conditions (e.g., filters, amplifies, and downconverts) the received RF signal, digitizes the conditioned signal, and provides samples. Demodulator 226 processes the samples as described below and provides demodulated data. A receive (RX) data processor 228 processes (e.g., deinterleaves and decodes) the demodulated data and provides decoded data 232. In general, processing by demodulator 226 and RX data processor 228 is complementary to processing by modulator 212 and TX data processor 234, respectively, at transmitter 211.

The controllers / processors 214 and 230 direct the operation at the transmitter 211 and the receiver 213, respectively. Memories 216 and 236 store program codes in the form of computer software and data used by transmitter 211 and receiver 213, respectively.

3 shows a block diagram of a design of a receiver unit 324 and a demodulator 326 in a receiver 213 in accordance with some embodiments of the present invention. Within receiver unit 324, receive chain 325 processes the received RF signal and provides I (in-phase) and Q (quadrature) baseband signals labeled I bb and Q bb . The receive chain 325 may perform low noise amplification, analog filtering, quadrature down-conversion, etc., as desired or needed. An analog-to-digital converter (ADC) 327 digitizes the I and Q baseband signals at a sampling rate of f adc from the sampling clock 323 and provides I and Q samples labeled I adc and Q adc . In general, the ADC sampling rate f adc may be related to the symbol rate f sym by any integer or non-integer factor.

Within the demodulator 326, the pre-processor 329 performs pre-processing on I and Q samples from an analog-to-digital converter (ADC) 327. For example, the pre-processor 329 can remove the DC (DC) offset and remove the frequency offset. Input filter 331 filters samples from pre-processor 329 based on a particular frequency response and provides input I and Q samples labeled I in and Q in . The input filter 331 may filter the I and Q samples to suppress images caused by sampling by the analog-to-digital converter (ADC) 327 as well as jammers. The input filter 331 may also perform sample rate down conversion from, for example, 24X oversampling to 2X oversampling. Data filter 333 filters input I and Q samples from input filter 331 based on different frequency responses and provides output I and Q samples labeled I out and Q out . The input filter 331 and the data filter 333 may be implemented with finite impulse response (FIR) filters, infinite impulse response (IIR) filters, or other types of filters. The frequency responses of input filter 331 and data filter 333 may be selected to achieve good performance. In one design, the frequency response of the input filter 331 is fixed and the frequency response of the data filter 333 is configurable.

The ACI detector 337 receives input I and Q samples from the input filter 331 and detects adjacent-channel-interference (ACI) in the received RF signal and detects the adjacent-channel-interference (ACI) indicator 339 to the data filter 333. The neighbor-channel-interference (ACI) indicator 339 indicates whether neighboring channel-interference (ACI) is present and if adjacent-channel-interference (ACI) is present at +200 kHz Centered high RF channel and / or due to a lower RF channel centered at -200 kHz. In order to achieve the desired performance, the frequency response of the data filter 333 may be adjusted based on the neighbor-channel-interference (ACI) indicator 339.

The equalizer / detector 335 receives the output I and Q samples from the data filter 333 and performs equalization, matched filtering, detection and / or other processing on the samples. For example, equalizer / detector 335 may implement a Maximum Likelihood Sequence Estimator (MLSE) that determines the sequence of I and Q samples and the sequence of symbols most likely to have been transmitted given a channel estimate.

GSM uses a combination of time division multiple access (TDMA) and frequency division multiple access (FDMA) for the purpose of sharing spectrum resources. GSM networks typically operate in multiple frequency bands. For example, in the case of uplink communications, GSM-900 typically uses radio spectrum in the 890-915 megahertz (MHz) bands (base station to base transceiver station). For downlink communications, the GSM 900 uses 935-960 MHz bands (from the base station 102 to the wireless communication device 104). In addition, each frequency band is divided into 200 kHz carrier frequencies to provide 124 RF channels spaced at 200 kHz. GSM-1900 uses 1850-1910 MHz bands for the uplink and 1930-1990 MHz bands for the downlink. Similar to GSM 900, FDMA divides the spectrum for both uplink and downlink into carrier frequencies of 200 kHz-wide. Similarly, GSM-850 uses the bands 824-8490 MHz for the uplink and 869-894 MHz for the downlink, while GSM-1800 uses the bands 1710-1785 MHz for the uplink and downlink Band of 1805 - 1880 MHz.

An example of a conventional GSM system is the " Technical Specification 3rd Generation Partnership Project ", Technical Specification Group GSM / EDGE Radio Access Network, Multiplexing and multiple access on the radio path Release 4) "is identified in the technical specification document 3GPP TS 45.002 V4.8.0 (2003-06).

In GSM, each channel is identified by a specific absolute radio frequency channel (ARFCN). For example, ARFCN 1-124 is assigned to the GSM 900 channels while ARFCN 512-810 is assigned to the GSM 1900 channels. Similarly, ARFCN 128-251 is assigned to the GSM 850 channels while ARFCN 512-885 is assigned to the GSM 1800 channels. Also, each base station 102 is assigned one or more carrier frequencies. Each carrier frequency is divided into eight time slots (labeled as timeslots 0 through 7) using TDMA such that eight consecutive time slots are allocated to one TDMA with a duration of 4.615 milliseconds (ms) Thereby forming a frame. The physical channel occupies one timeslot within the TDMA frame. Each active wireless communication device 104 or user is assigned one or more timeslot indices for the duration of the call. The user-specific data for each wireless communication device 104 is transmitted in the time slot (s) allocated to that wireless communication device 104 and in the TDMA frames used for the traffic channels.

Figure 4 illustrates exemplary frame and burst formats in Global System for Mobile Communications (GSM) according to some embodiments of the present invention. The timeline for transmission is divided into multi-frames 463 in accordance with some embodiments of the present invention. For traffic channels used to transmit user-specific data, each multi-frame 463 in this example includes 26 TDMA frames 464 labeled as TDMA frames 0-25. Traffic channels are transmitted in TDMA frames 0 to 11 and TDMA frames 13 to 24 of each multi-frame 463. The control channel is transmitted in the TDMA frame 12. No data is transmitted in the idle TDMA frame 25, which is used by the wireless communication devices 104 to perform measurements of signals transmitted by the neighboring base stations 102.

Each time slot within a frame is also referred to as "burst" 465 in GSM. Each burst 465 includes two tail fields, two data fields, a training sequence (or midamble) field, and a guard period GP. The number of symbols in each field is shown in parentheses. The burst 465 includes symbols for the tail, data, and midamble fields. In the guard period, no symbols are transmitted. The TDMA frames of a particular carrier frequency are numbered and formed into groups of 26 or 51 TDMA frames 464, referred to as multi-frames 463.

FIG. 5 illustrates an exemplary spectrum 500 in a GSM system according to some embodiments of the present invention. In this example, the five RF modulated signals are transmitted on five RF channels spaced by 200 kHz. The RF channel is shown as having a center frequency of 0 Hz. Two adjacent RF channels have center adjacent-channel-interference (ACI) frequencies of +200 kHz and -200 kHz from the center frequency of the desired RF channel. The next two closest RF channels (referred to as the blockers or non-adjacent RF channels) are the center adjacent channel-interference (ACI) frequencies of + 400 kHz and -400 kHz from the center frequency of the desired RF channel . For the sake of simplicity, other RF channels, not shown in FIG. 5, may be present in the spectrum 500. In GSM, the RF modulated signal is generated at a symbol rate of f sym = 13000/40 = 270.8 symbols / second (ksps) and has -3 dB (dB) bandwidth up to 135 kHz. Thus, the RF modulated signals on adjacent RF channels may overlap one another at the edges, as shown in FIG.

In GSM / EDGE, the frequency bursts FB are used to cause the wireless communication devices 104 to synchronize their local oscillator (LO) to the base station 102 local oscillator (LO) using frequency offset estimation and correction And is periodically transmitted by the base station 102 to allow it. These bursts include payloads that are all "0 " and singletons corresponding to training sequences. The payload of all of the frequency bursts "0 " is a constant frequency signal or a singleton burst. In the power mode, the wireless communication device 104 continues to hunt for the frequency burst from the list of carriers. Upon detection of the frequency burst, the wireless communication device 104 will estimate the frequency offset for its nominal frequency of 67.7 kHz from the carrier. The wireless communication device 104 local oscillator (LO) will be corrected using the estimated frequency offset. In power up mode, the frequency offset may be +/- 19kHz. The wireless communication device 104 may periodically wake up to monitor the frequency burst to maintain its synchronization in the standby mode. In standby mode, the frequency offset is within ± 2kHz.

One or more modulation schemes are used in GERAN systems to communicate information such as voice, data and / or control information. Examples of modulation schemes may include Gaussian minimum shift keying (GMSK), M-ary quadrature amplitude modulation (QAM) or M-ary PSK (phase shift keying), where M = 2 n , Is the number of bits encoded in the symbol period for the modulation scheme. GMSK is a constant envelope binary modulation scheme that allows raw transmission at a maximum rate of 270.83 kilobits per second (Kbps).

General Packet Radio Service (GPRS) is a non-voice service. This allows information to be transmitted and received via the mobile telephone network. This complements Circuit Switched Data (CSD) and Short Message Service (SMS). GPRS uses the same modulation schemes as GSM. GPRS allows the entire frame (all 8 time slots) to be used by a single mobile station at the same time. Thus, higher data throughput rates are achievable.

The EDGE standard uses both GMSK modulation and 8-PSK modulation. Also, the modulation type may vary from burst to burst. The 8-PSK modulation of EDGE is a linear 8-level phase modulation with 3π / 8 rotation, while the GMSK is a nonlinear time-pulse-shape frequency modulation. However, the particular GMSK used in GSM can be approximated by linear modulation (e.g., two-level phase modulation with pi / 2 rotations). The symbol pulse of the approximated GSMK and the symbol pulse of 8-PSK are identical. The EGPRS2 standard uses GMSK, QPSK, 8-PSK, 16-QAM and 32-QAM modulation. The modulation type may vary from burst to burst. In EGPRS2, Q-PSK, 8-PSK, 16-QAM and 32-QAM modulations are linear 4-level, 8-level, 16-QAM with 3π / 4, 3π / 8, Level and 32-level phase modulations, while GMSK is a non-linear Gaussian-pulse-shaped frequency modulation. However, the particular GMSK modulation used in GSM can be approximated by linear modulation (e.g., two-level phase modulation with pi / 2 rotations). The symbol pulse of the approximated GSMK and the symbol pulse of 8-PSK are identical. The symbol pulses of Q-PSK, 16-QAM and 32-QAM can utilize narrow or wide pulse shapes in the spectrum.

The wireless device 600 may be a base station 102 or a wireless communication device 104. Transmit circuitry 641 and receive circuitry 643 may allow transmission and reception of data, such as audio communications, between wireless device 600 and a remote location. The transmitting circuit 641 and the receiving circuit 643 may be coupled to the antenna 640.

The processing unit 646 controls the operation of the wireless device 600. The processing unit 646 may also be referred to as a central processing unit (CPU). A memory 647, which may include both read only memory (ROM) and random access memory (RAM), provides instructions and data to the processing unit 646. Portions of memory 647 may also include non-volatile random access memory (NVRAM).

The various components of the wireless device 600 are coupled together by a bus system 649 that may include a power bus, a control signal bus, and a status signal bus in addition to the data bus. For clarity, the various buses are shown in Fig. 6 as bus system 649.

[ These commands may be executed by the controller / processor (s) of the wireless device 600. Alternatively or in conjunction therewith, the steps of the methods discussed may be stored as instructions in the form of software or firmware 648 located in the memory 647 of the wireless device 600. These instructions may be executed by the processing unit 646 of the wireless device 600 of FIG.

Figure 7 illustrates an example of a transmitter structure and / or process in accordance with some embodiments of the present invention. The transmitter structure and / or process of FIG. 7 may be implemented in a wireless device, such as wireless communication device 104 or base station 102. The functions and components shown in Fig. 7 may be implemented by software, hardware, or a combination of software and hardware. Other functions may be added to FIG. 7 in addition to or instead of the illustrated functions.

In FIG. 7, a data source 750 provides data d (t) 751 to a frame quality indicator (FQI) / encoder 752. The frame quality indicator (FQI) / encoder 752 may attach a frame quality indicator (FQI), such as a cyclic redundancy check (CRC), to the data d (t). The frame quality indicator (FQI) / encoder 752 may further encode data and a frame quality indicator (FQI) using one or more coding schemes to provide encoded symbols 753 have. Each coding scheme may include one or more types of coding, such as, for example, convolutional coding, turbo coding, block coding, repetition coding, other types of coding, or no coding at all. Other coding schemes may include Automatic Repeat Request (ARQ), Hybrid ARQ (H-ARQ), and incremental redundancy repeat techniques. Different types of data can be encoded in different coding schemes.

Interleaver 754 interleaves the encoded data symbols 753 in time and generates symbols 755 to combat fading. Interleaved symbols 755 may be mapped to a predefined frame format by frame format block 756 to generate frame 757. [ In one example, frame format block 756 may specify frame 757 as consisting of a plurality of sub-segments. The sub-segments may be any contiguous portions of the frame 757 along a given dimension, such as, for example, time, frequency, code or any other dimension. The frame 757 may consist of a plurality of such fixed sub-segments, each sub-segment including some of the total number of symbols allocated to the frame 757. In one example, interleaved symbols 757 are segmented into a plurality (S) of sub-segments that make up frame 757.

Frame format block 756 may further specify, for example, the inclusion of control symbols (not shown), along with interleaved symbols 755. These control symbols may include, for example, power control symbols, frame format information symbols, and the like.

A modulator 758 modulates the frame 757 to generate modulated data 759. Examples of modulation techniques include binary phase shift keying (BPSK) and quadrature phase shift keying (QPSK). The modulator 758 may also repeat the sequence of modulated data.

8 is a block diagram illustrating an example of a wireless communication system 800 in which the systems and methods disclosed herein may be utilized. The wireless communication system 800 may be one configuration of the wireless communication system 100 described with respect to FIG. For example, the base station 802 and the wireless communication device 804 of FIG. 8 may correspond to the base station 102 and the wireless communication device 104 of FIG.

The base station 802 may include a page message transmission module 866. The page message sending module 866 may send messages to the wireless communication device 804 based on the mode of operation of the wireless communication device 804. [ For example, if the wireless communication device 804 is in a semi-non-discrete receive (non-DRx) mode, the page message transmission module 866 may determine that the wireless communication device 804 is in a non- And may transmit page messages to the wireless communication device 804 less frequently than when the wireless communication device 804 is in discontinuous reception (DRx) mode.

In the DRx mode, the wireless communication device 804 may preserve the battery by limiting the amount of time it takes the wireless communication device 804 to monitor incoming transmissions, such as pages. However, in DRx mode, the wireless communication device 804 may have to wait longer periods between reading incoming pages because the incoming pages are not transmitted frequently enough.

In the non-DRX mode, the wireless communication device 804 continues to monitor incoming transmissions, such as pages. However, in the DRx mode, the wireless communication device 804 may consume too much power by attempting to read messages in page blocks that are not sent any page messages by the base station 802.

The page message transmission module 866 may include a multi-frame (MF) transmission module 867 and a timer module 868. The multi-frame (MF) transmission module 867 may transmit multi-frame (MF) radio blocks to the wireless communication device 804. For example, a multi-frame (MF) radio block may be a 51-multiframe (MF) radio block. Timer module 868 may include a non-DRx timer 869a and a semi-DRx timer 871a.

The wireless communication device 804 may include a page message receiving module 874 and a paging group 880. The page message receiving module 874 may include a multi-frame (MF) receiving module 875, a non-DRx timer 869b and a semi-DRx timer 871b. The paging group 880 may include a paging index 881.

One or more of the wireless communication devices 804 may belong to the paging group 880. Paging group 880 may indicate when to read multi-frame (MF) radio blocks. For example, the paging group 880 may indicate to the wireless communication device 804 when to read a multiframe (MF) radio block, such as once every third 51-multiframe (MF) cycle . The paging group 880 may be determined by the international mobile subscriber identity of the wireless communication device 804. [

The paging index 881 may indicate which paging block slot to read in the multi-frame (MF) radio block. The wireless communication device 804 may receive messages from the base station 802 at any of the 51-multiframes MF corresponding to the paging index 881 of the wireless communication device 804 itself. Additional discussion regarding paging groups 880 and paging index 881 will be provided below. A non-DRX timer 869b and a semi-DRX timer 871b will also be described below.

A multi-frame (MF) receive module 875 on the wireless communication device 804 may receive multi-frame (MF) radio blocks from the base station 802. For example, a multi-frame (MF) radio block may be a 51-multiframe (MF) radio block.

The wireless communication device 804 may operate in various operational modes, such as idle mode, dedicated mode, and packet transmission mode. Because the wireless communication device 804 switches between operating modes, the base station 802 may receive and maintain such information. For example, the base station 802 may store the mode of operation of the wireless communication device 804 in the page message transmission module 866. Recognizing the current mode of operation of the wireless communication device 804 allows the wireless communication system 800 and the base station 802 to determine how to transmit communications to the wireless communication device 804. [ For example, the base station 802 may determine the mode of operation of the wireless communication device 804 to determine when to send an assignment message to the wireless communication device 804 using the paging group 880 of the wireless communication device 804 It can also be used.

GERAN specifications define two modes of operation for wireless communication device 804 in idle mode: Discrete Receive (DRx) mode and Non-Discrete Receive (non-DRx) mode. The DRx mode allows the wireless communication device 804 to preserve the battery by limiting the amount of time it takes to monitor the transmissions that the wireless communication device 804 is receiving. The non-DRx mode disables the DRx mode at the wireless communication device 804. DRx and non-DRx modes will be further described below.

According to some embodiments of the present invention, an additional mode, called a semi-DRx mode, may be employed. In the semi-non-DRX mode, the wireless communication device 804 is configured to communicate more frequently when the wireless communication device 804 is in the DRx mode and less frequently when the wireless communication device 804 is in the non- For example. For example, in the semi-DRx mode, the wireless communication device 804 may monitor the paging block once for each multi-frame (MF) cycle. The multi-frame (MF) cycle may be a 51-multiframe (MF) cycle.

In DRx mode, the wireless communication device 804 may monitor only the radio blocks on the Common Control Channel (CCCH), which correspond to its paging group 880 only. The paging group 880 may be calculated by the wireless communication device 804 and the wireless communication network (i.e., wireless communication system) 800 using the formulas defined in 3GPP TS 45.002. Thus, the wireless communication device 804 may read only one radio block corresponding to the paging index 881 of the wireless communication device 804 every n-th 51-multiframe. The parameter n may be 2, 3, 4, 5, 6, 7, 8, or 9, depending on the particular network configuration. The paging index 881 may be calculated by the wireless communication device 804 and the wireless communication network 800 using the formula defined in 3GPP TS 45.002. In DRx mode, the wireless communication device 804 may preserve battery power. However, this power conservation may sacrifice excess delay when attempting to initiate downlink data transmission.

In the DRx mode, the wireless communication device 804 may have various monitoring features. For example, in the shortest DRx cycle mode, the wireless communication device 804 may monitor the paging block every second 51-multiframe (MF). However, in the longest Rx cycle mode, the wireless communication device 804 may monitor the paging block every ninth 51-multiframe. The frequency with which the wireless communication device 804 monitors the paging block may be controlled by the base station 802 and / or broadcast information from the wireless communication system. It should be noted that the above-described examples of the DRx mode assume that a split paging cycle is not employed.

Before entering the DRx mode, the wireless communication device 804 may first enter the non-DRx mode. In the non-DRX mode, the wireless communication device 804 may monitor all blocks on the common control channel (CCCH) for the wireless communication device 804. In the non-DRx mode, the wireless communication device 804 may receive a new assignment message for downlink data transmission with minimal delay.

The non-DRx mode may be divided into four different groups depending on which type of information the wireless communication device 804 is using for the GPRS connection. The four groups are the transmission non-DRx mode, the mobility management (MM) non-DRx mode, the network control (NC) non-DRx mode and the multimedia broadcast / multicast service (MBMS) non-DRx mode (3GPP TS 44.060 Reference). The systems and methods of the present invention may be most useful when the wireless communication device 804 enters the transmission non-DRx mode, although the semi-DRx mode may be employed with all non-DRx modes.

In the transmit non-DRx mode, the wireless communication device 804 may transmit user data before entering the idle mode (e.g., DRx mode). The transmit non-DRx mode is generally the most common non-DRx mode. In the mobility management (MM) non-DRx mode, the wireless communication device 804 may send mobility management messages before entering the idle mode. The mobility management (MM) non-DRx mode generally occurs when the wireless communication device 804 is performing registration, routing area update, or location area update. In the MBMS non-DRx mode, the wireless communication device 804 may transmit MBMS data. The MBMS may not be implemented by the wireless communication device 804. In the network controlled (NC) non-DRx mode, the wireless communication device 804 may send network controlled measurement reports prior to entering the idle mode. Network control (NC) Non-DRx mode is supported, but is not normally used.

The duration of the transmit non-DRx mode may be the duration of the values of the non-DRx timer 869. [ The value (e.g., time) of the non-DRX timer 869b may be a minimum value of the NON-DRX-TIMER-MAX parameter and the NON-DRX-TIMER parameter. The NON-DRX-TIMER-MAX parameter may be broadcast in the GPRS cell options. For example, the NON-DRX-TIMER-MAX parameter may be determined by the timer module 868 on the base station 802 and broadcast to the wireless communication device 804. [ The NON-DRX-TIMER parameter may be determined by the manufacturer of the wireless communication device 804 and may be signaled to the network via GPRS mobility management (GMM) procedures by the wireless communication device 804. The duration of the transmission non-DRx mode allows a trade-off between the delay in establishing a connection with the wireless communication device 804 by the wireless communication network and the power consumption in the wireless communication device.

The delay is the excess time it takes the wireless communication network 800 to reconnect with the wireless communication device 804 and attempt to establish a connection with the wireless communication device 804, e.g., a downlink temporary block flow (TBF). For example, if the non-DRX timer 869b (e.g., NON-DRX-TIMER) is set to zero, the network may allocate an allocation of downlink temporary block flow (TBF) for the shortest paging cycle to the wireless communication device 804) to 480 msec. This can result in poor performance, especially for bus-tie applications. If the wireless communication device 804 is set to a non-zero value for the non-DRX timer 869b, the wireless communication device 804 may waste power in monitoring the unnecessary downlink radio blocks.

In accordance with some embodiments of the invention, both power consumption and delay may be reduced by the wireless communication device 804 employing a semi-DRx mode. Semi-non-DRx mode combines the best features of both DRx mode and transmission non-DRx mode. The semi-non-DRx mode may also be referred to as a semi-transmission non-DRx mode because it is a new transmission non-DRx mode. Although the semi-non-DRx mode is applied to the transmit non-DRx mode, it is equally applicable to the mobility management (MM) non-DRx mode, the network control (NC) non-DRx mode, and / or the MBMS non- Should be recognized.

While in semi-non-DRX mode, the wireless communication device 804 is configured to transmit a paging index corresponding to the paging index for the wireless communication device 804 for the same paging index 881 in every 51- Wireless blocks may also be monitored. The wireless communication device 804 may either remain in the semi-non-DRx mode for the duration of the non-DRX timer 869b (e.g., NON-DRX-TIMER) or during the duration of the semi-DRX timer 871b have. Semi-DRX timer 871b may also be referred to as SEMI-NON-DRX-TIMER.

One advantage of the semi-DRX mode is that connections such as downlink temporary block flow (TBF) may be established with a maximum delay of 235 msec (i.e., one 51-multiframe). Although the power consumption of the wireless communication device 804 may increase slightly, such an increase may still be significantly lower than the current power consumption of the wireless communication device 804 in the transmission non-DRx mode. Estimates of power consumption for legacy mode (i.e., non-DRx mode) and new semi-DRx mode (i.e., semi-transmission rate-DRx) are provided in Table 1 below.

Figure 112014051754719-pct00001

In Table 1, X i represents power consumption with paging cycle i. The parameter i may be 2, 3, 4, 5, 6, 7, 8, or 9 depending on the particular network configuration. Additionally, the transmit non-DRx mode of Table 1 assumes that one broadcast control channel (BCCH) is read every 51-multiframe (MF).

In DRx mode, the power consumption X i depends on the paging cycle. For example, a wireless communication device 804 that reads a radio block for every two 51-multiframes (MFs) (i. E., X 2 ) 4 ) More power is consumed than when reading a radio block. The power consumption in DRx mode may be as follows: X 2 > X 3 > X 4 > X 5 > X 6 > X 7 > X 8 > X 9 .

In both the non-DRx mode and the semi-DRx mode, the power consumption is independent of the paging cycle i. For the non-DRx mode, the power consumption estimates shown in Table 1 exclude the frequency correction channel (FCCH), synchronization channel (SCH), and IDLE frames from the 51-multiframes MF. It may also be recognized that to receive one radio block, the wireless communication device 804 is required to receive exactly four frames. Figure 10, described below, provides examples of multi-frame (MF) radio blocks.

Specification changes may be required to allow the wireless communication device 804 to assume a semi-non-DRx mode. In particular, the specification change may include adding an indication to the GPRS cell options to signal to the wireless communication device 804 that the base station 802 supports a semi-non-DRx mode. Table 2 below shows how the existing NON-DRX-MAX timer information is used for the semi-transmission non-DRx mode by the wireless communication system (e.g., wireless communication network 800) An example of an element extension is provided.

Figure 112014051754719-pct00002

If the SEMI-NON-DRX-MODE indicates that a NON-DRX-MAX timer is to be employed, the values of the semi-DRx timer 871b may be the same as the values defined for the non-DRx timer 869b. In other configurations, the semi-DRX timer 871b may have newly defined values. Table 3 below provides an example of a GPRS cell options information element when a new NON-DRX-MAX timer is used (i.e., a semi-DRx timer 871b).

Figure 112014051754719-pct00003

The specification change may also include an indication in the wireless communication device 104 radio access capability (RAC) to signal that the wireless communication device 104 supports the semi-non-DRx mode. An example of a wireless communication device 104 radio access capability (RAC) information element is provided below in Table 4, where the MS refers to a mobile station (i.e., wireless communication device 104).

An alternative approach to using the GPRS cell options for signaling network performance for the semi-transmit non-DRx mode is that the wireless communication network 800 is capable of handling wireless transmissions in wireless link control / media access control (RLC / MAC) To command the communication device 804 to command it. The radio link control / media access control (RLC / MAC) messages may be displayed on the wireless communication device 804 for use in the semi-DRX mode.

An advantage of the radio link control / media access control (RLC / MAC) message is that the wireless communication network 800 determines whether the semi-transmission non-DRx mode is more suitable or the legacy transmission non- You can decide. For example, for services such as instant messengers, the response time from a user on the wireless communication device 804 may be very slow. Here, the semi-transmission non-DRx mode may be more suitable. The legacy transmission non-DRx mode may be more suitable if the request is to use a service (e.g., web browsing) whose response time is much faster than one multi-frame.

The exemplary coding shown in Table 2 or Table 3 may be used to select a suitable downlink wireless channel, such as Packet Uplink Acknowledgment / Negative Acknowledgment (ACK / NACK), Packet Uplink Assignment Message, Packet Downlink Assignment Message, Packet Timeslot Reconfiguration Message, May be added as extensions to link control / media access control (RLC / MAC) messages. The wireless communication device 804 may signal support for the semi-transmission non-DRx mode in mobile station (MS) radio access capability, as shown in Table 4 below.

Figure 112014051754719-pct00004

Existing non-DRx timer parameters may be used to signal the duration of the semi-DRx mode. For example, a conventional non-DRx timer parameter may determine both the value of the non-DRx timer 869b and the value of the semi-DRx timer 871b. However, cells that do not support the semi-non-DRx mode may cause the wireless communication device 804 to use the legacy non-DRx mode. This may not be desirable since it may significantly increase idle mode power consumption, as shown in Table 1 above. It may be more desirable to introduce a new timer value for the semi-DRx mode, such as semi-non-DRx timer 871, A new timer value (e.g., the value of the semi-DRx timer 871) may require a new information element carried by the ATTACH REQUEST message and the ROUTING AREA UPDATE REQUEST message. New information elements to be added to the GPRS mobility management (GMM) messages are shown in Table 5 below.

Table 6 below provides definitions of non-DRx timers for use in current systems and methods. The specific values of the semi-non-DRX timer 871b may be equal to the values defined for the non-DRx timer in 3GPP TS 24.008 or the values proposed above in Table 3.

9 is a flow chart illustrating mode transitions for a wireless device in accordance with some embodiments of the present invention. The mode transitions may be performed by a wireless device, such as the wireless communication device 104. The base station 102 may track different mode transitions of the wireless communication device 104. The wireless communication device 104 may first enter a packet transmission mode (902). The wireless communication device 104 may switch to a packet idle mode, e.g., a non-DRx mode, a semi-DRx mode, or a DRx mode when the packet transmission mode ends (i.e., data transmission is complete).

The wireless communication device 104 may determine whether the semi-DRX timer 871b on the wireless communication device 104 has a value greater than zero. As described above, the semi-DRX timer 871b is configured to determine how long the wireless communication device 104 has been in the semi-DRx mode (i.e., before it enters the DRx mode (i.e., the DRx packet idle mode) Semi-non-DRx packet idle mode) of the wireless communication device 104 (or not at all). The values for the semi-DRX timer 871b may be, for example, 0, 1, 2, 4, 8, 16, 32, or 64 seconds. Other values for the semi-non-DRX timer 871b may also be used. The wireless communication device 104 may also determine whether the non-DRx timer 869b is greater than zero.

If the network does not support the semi-non-DRX mode, the wireless communication device 104 may not be able to use the semi-DRX mode. If the network supports a semi-DRX mode with NON-DRX-MAX, the wireless communication device 104 can communicate with the semi-DRX timer 869b supported by the wireless communication device 104 and the NON You can also select the minimum value for the -DRX-MAX timer. If the network supports a semi-DRX mode with the new SEMI-NON-DRX-MAX, then the wireless communication device 104 is able to communicate with the semi-DRX timer 871b supported by the wireless communication device 104, May select the minimum value of the supported semi-DRX timer 871a (e.g., SEMI-NON-DRX-MAX timer). Thus, if the wireless communication device 104 has a semi-DRX timer 871b with a value greater than zero, then the network may use a semi-DRx mode with a NON-DRX-MAX timer or a SEMI-NON- .

When the data transmission is complete, the wireless communication device 104 does not have a semi-DRX timer 871b with a value greater than zero (e.g., the value of the semi-non-DRx timer 871b is zero) If the communication device 104 does not have a non-DRx timer 869b having a value greater than 0 (e.g., the value of the non-DRx timer 869b is 0) and the wireless communication device 104 determines 904), the wireless communication device 104 may enter the direct DRx mode (906).

If the wireless communication device 104 determines that the wireless communication device 104 has the same semi-DRx timer 871b as 0 but has a non-DRx timer 869b that is greater than 0, The wireless communication device 104 may initiate 910 a semi-non-DRX timer 871b and enter 912 the non-DRx mode for the duration of the non-DRx timer 869, . The wireless communication device 104 may then switch to the DRx mode and enter the DRx mode (906) when the non-DRx timer 869b has expired (914).

If the wireless communication device 104 determines 916 that the wireless communication device 104 has a semi-non-DRx timer with a value greater than zero, then the wireless communication device 104 determines A DRX timer may be started 918 and a semi-DRx mode may be entered 920. As described above, the semi-DRx mode may represent a new state or mode of DRx / non-DRx modes. When the semi-non-DRX timer 871b expires 922, the wireless communication device 104 may switch from the semi-non-DRx mode and enter the DRx mode (906).

9, in some configurations, the semi-DRx mode may replace the non-DRx mode on the wireless communication device 104. [ In other words, the wireless communication device 104 may include functionality for a semi-DRx mode or a non-DRx mode.

In another configuration (not shown), the wireless communication device 104 may include functionality for both semi-non-DRx and non-DRx modes. For example, if the wireless communication device 104 has a semi-DRX timer 871b having a value greater than zero and a non-DRx timer 869b having a value greater than zero when the data transfer is complete, The communication device 104 may switch the semi-non-DRAM timer 871b to the semi-non-DRAM mode to start. When the semi-non-DRX timer 871b expires, the wireless communication device 104 may switch from the semi-non-DRx mode to the non-DRx mode. The wireless communication device 104 may enter the non-DRx mode for the duration of the non-DRx timer 869. [ The wireless communication device 104 may switch from the non-DRx mode to the DRx mode when the non-DRx timer 869b has expired.

In another arrangement, it is assumed that when the data transfer is complete, the wireless communication device 104 has a semi-DRx timer 871b having a value greater than zero and a non-DRx timer 869b having a value greater than zero If the communication device 104 determines 924, the wireless communication device 104 may initiate 926 a non-DRx timer 869b and enter 928 a non-DRx mode. When the non-DRX timer 869b expires 930, the wireless communication device 104 may switch from the non-DRx mode and enter 921 the semi-non-DRx mode. In other words, the wireless communication device 104 may initiate (932) a semi-non-DRx timer 871b and enter 921 a semi-non-DRx mode. The wireless communication device 104 may enter a semi-non-DRx mode for the duration of the semi-non-DRX timer 871b (920). The wireless communication device 104 may switch from the semi-DRx mode and enter 906 the DRx mode when the semi-non-DRx timer 871b expires (922).

10 is a block diagram illustrating wireless blocks read by a wireless communication device 104 during a semi-DRX mode in accordance with some embodiments of the present invention. Each 51-multiframe (MF) 1084a-e may have 51 frames (see 3GPP TS 45.002). Each 51-multiframe (MF) 1084 may be numbered from 00 to 50 in order. Although five 51-multiframes (MFs) 1084a-e are shown, only one and as many as n may be employed, where n should be recognized as representing an integer value. For example, 12, 35, 80, or 104 multiframes (MFs) may be employed in each cycle.

Different channels may be associated with each frame. For example, a frequency correction channel (FCCH) may be associated with frames 00, 10, 30 and 40. A synchronization channel (SCH) may be associated with frames 01, 11, 21, 31, and 41. The broadcast control channel (BCCH norm) may be associated with frames 02, 03, 04 and 05. In some arrangements, the optional broadcast control channel (BCCH ext) may be associated with frames 06, 07, 08, and 09 (not shown).

In addition, the frames may be associated with a paging index 1086. Nine paging indices 1086a-i may be associated with each 51-multiframe (MF) 1084a-e (nine paging indices are added to the first BCCH block).

For the embodiment shown in FIG. 10, the wireless communication device 104 is assigned paging index 7 (1086h). Thus, the wireless communication device 104 may also monitor and read the BCCH radio block 1085 for every 51-multiframe (MF) 1084a-e. If the network also supports (extended) BCCH ext, the wireless communication device 104 may also monitor and read BCCH radio blocks corresponding to BCCH ext every every 51-multiframe (MF) 1084a-e . The wireless communication device 104 may transmit the wireless blocks corresponding to its paging index 1086 and optionally the BCCH 1084a-e for every 51-multiframe (MF) 1084a-e until the semi-DRX timer 871b expires, It may continue to read the radio block (s). At the expiration of the semi-non-DRX timer 871b, the wireless communication device 104 may switch to the DRx mode (where, in every n-th 51-multiframe (MF) 1084a-e, Only the radio block corresponding to the radio block is read). The use of the semi-non-DRX mode allows for faster access allocations such as downlink temporary block flow (TBF) allocations while minimizing power consumption at the wireless communication device 104.

In some embodiments of the present invention, the wireless communication device 104 may monitor for pages more frequently than once per multi-frame (MF) paging cycle 1084. For example, the wireless communication device 104 may monitor and read a radio block 1087 corresponding to more than one paging index 1086 per multi-frame (MF) cycle 1084. [ In other words, the wireless communication device 104 may monitor for pages in the range of paging indices 1086. [ The frequency of monitoring may be fixed or may vary. For example, the wireless communication device 104 may monitor for pages in accordance with a range of paging indices 1086 during a first time period, and then the wireless communication device 104 may monitor for pages over a second time period May be monitored for pages in accordance with other ranges of paging indices 1086. < RTI ID = 0.0 > These ranges may be dynamic. Thus, pages may be read more frequently in the semi-DRx mode than in the non-DRx mode, and less frequently in the semi-DRx mode than in the DRx mode.

In some embodiments of the present invention, the wireless communication device 104 may monitor for pages during the range of (MF) paging cycles 1084. For example, the wireless communication device 104 may monitor for pages during a first multi-frame (MF) 1084a cycle and a second multi-frame (MF) 1084b cycle, ) 1084c. ≪ / RTI > The wireless communication device 104 may repeat this pattern during the following three multi-frame (MF) 1084 cycles. Alternatively, the wireless communication device 104 may use a different pattern to monitor for pages. Thus, the pages may be read more frequently in the semi-DRx mode than in the non-DRx mode, and less frequently in the semi-DRx mode than in the DRx mode.

In some embodiments of the present invention, the wireless communication device 104 may monitor Broadcast Control Channel (BCCH) radio blocks 1085 over a range of multi-frame (MF) cycles 1084. For example, the wireless communication device 104 may monitor broadcast control channel (BCCH) radio blocks 1085 only once for every five multi-frame (MF) cycles 1084, DRx paging block 1087 in each of the < RTI ID = 0.0 > MF) cycles 1084. < / RTI > In another example, the wireless communication device 104 may receive three times for every five multiframe (MF) cycles 1084, such as all other multiframe (MF) cycles 1084, a broadcast control channel (BCCH) Lt; RTI ID = 0.0 > 1085 < / RTI > Thus, broadcast control channel (BCCH) radio blocks may be read less frequently in the semi-DRx mode than in the non-DRx mode, and / or less frequently in the semi-DRx mode than in the DRx mode.
